IMPROVEMENT IN MACHINES FOR MAKING AUGERS.

Specication forming part of Letters Patent No. 41,@22, dated March l,18if4.

To all whom, it may concern.:

Be it known that IsrAH TOWER, of the city of Rochester, county ofMonroe, and State of New York, did invent a new and usefulMachine forTwisting Augers; and I do hereby declare that the following is a full,clear, and exact description of the construction and operation of thesame, reference being had to the annexed drawings, making a part of thisspecification, in which- Figure 1 is a perspective view of the machinewhen in position to receive the plate to be twisted. Fig. 2 is anelevation of a pair of plates in the position when the auger is twisted.Fig. 3 is an elevation of a single plate. Fig. 4 is a plan of a pair ofplates in the position when the auger is twisted. Fig. 5 is a plan of asingle plate.

The nature of this invention consists in making a series of steel platesin pairs, and then placing one pair top of the other on a platform tothe required height, these plates being shaped in the center to form adie, and

then a cover put on, bolted with strong bolts to the platform. Theseplates are so arranged thatby turning them theupperpair turns oneeightharound, when it catches the next pair, and that pair, going one-eightharound, catches the next, and so on until all are turned, and a iatpiece or bar of steel or iron, of which to make an auger, being heatedand putin between them, and the plates turned, the iron is twistedperfectly even and true. Then by changing the relative position of eachplate to its mate by moving the upper one back into a certain position,the auger or twisted plate will of itself drop out of the machine.

To enable others skilled in the art to make and use this invention, Iwill proceed to describe its construction and operation by referring tothe annexed drawings and letters ofl reference marked thereon.

A, Fig. l, shows an iron platform on which the plates rest, and to whichthe lower plate is made fast.

B, Fig. l, shows an iron cover or top to the machine.

The parts marked C, Fig. 1,' show strong iron bolts, which hold theplatform and cover together, and thereby keep the plates in position.

The parts marked l), Fig. 1., show nibs which form a part of the upperplate of the series, and by which the plates are moved by means of aleyer.

The parts marked E, Fig. 1, show blocks that form a part of the plates.v

The parts marked F, Fig. 1, are a part of the blocks marked E, Fig. 1.

Gr, Fig. 2, shows the edge of an upper'plate of a pair. H, Fig. 2, showsthe edge of an under plate of a pair.

The parts marked E, Fig. 2, are blocks forming a part of the plate Gr,and are the same as the blocks marked E, Fig. 1.

The p'arts marked F, Fig. 2, show a part of the block E, Fig. v2, andare the same as the blocks marked F, Fig. 1.

The parts marked K, Fig. 2, are blocks on the lower plate, H, Fig. -2,and correspond with the blocks on the upper plate, (marked E, Fig. 2.)

The parts marked L, Fig. 2, show blocks which form a part of the blocksK, Fig. 2, and which correspond with the blocks, F, Fig. 2.

M M, Fig. 3, show pieces which form a part of the plate, but are raisedon it, and are shaped so as to form a die, and give the required twistto the auger.

G, Fig. 4, shows the top ofthe plate Gr, Fig. 2.

The parts marked E, Fig. 4, show the tops ofthe blocks marked E, Fig. 2.

The parts marked F, Fig. 4, show the tops of the blocks marked F, Fig 2.

The parts marked K, Fig. 4, show the tops of the blocks marked K, Fig.2.

The parts marked L, Fig. 4, show the tops of the blocks marked L, Fig.2.

M M, Fig. 4, show pieces which are raised on the lower plate, the sidesof which are shown M M, Fig. 3.

The parts marked T, Fig. 4, show the pieces M M, Fig. 4, and M M, Fig.3, cut to form a die to give the required twist to the auger.

U U, Fig. 4, show grooves cut in the uppe plate to admit the rim or lipon the auger.

M M, Eig. 5, Show the top of the pieces M M, Fig. 4, and M M, Fig. 3. A

Now, it will be seen that by taking a flat piece of iron or steel,prepared for an auger, and iinished complete, except the twist and,point, andby heating it, and then putting it into the top of the machineat W, Fig. 1, and,

by means ofa lever, turning the upper plate in the direction shown bythe arrows on Fig. l, when lthe upper plate has moved oneeghth around,the block E on the upper plate strikes the block F ou the next lowerplate, and at the saune` time the block F on the lower plate, strikesthe block E on the neXt upper plate below, which carries them one-eightharound, when the blocks on these plates strike the blocks ou the nextlower plate, and so on, until `all the plates are turned, and, eachplate being so shaped in the center as to give its required portion of`twist to the auger, the auger must be twisted perfectly true. After thisis done, bychangin g the relative position ofone plate to the other ofthe pairs, by moving the upper plates back, so tliattlie block `E` onFig. 4,011 the upper plate, will come against the block K, Fig. 4, onthe lower plate,

the center or die is opened, so that the twisted auger will of itselfrun down through the 1n n.-

chine and out at the bottom. t

The advantages of this machine are, tirst, that the auger mustnecessarily be perfectly true, and therefore better than one made in theordinary way 5 second,the angers can be uished up in a flat bar beforebeing twisted, and thereby save a good deal of labor; third, angers canbe made a great deal quicker than in the ordinary way, and for thatreason made cheaper; fourth, any reasonable length of auger can betwisted perfectly true and straight, as the machine may be increased ordecreased at pleasure, by adding or removing plates.

Havin g thus described the construction and operation of this invention,what I claim as new, and desire to secure by Letters Patent,

A series of pla-tes constructed and operating in the manner and for thepurpose substair tially, as herein described and represented.`
